This paper presents a Key-Selective Patchwork Algorithm for audio watermarking. Two special subsets of the host signal features were selected to embed the watermark signal, adding a small constant value to one subset and subtracting the same to another patch. The method is based on wavelet domain and the watermark signals were embedded in approximation… CONTINUE READING
